Is pain on the outside of the left arm a symptom of cancer?

Pain on the outside of the left arm is usually not a sign of cancer, but cancer can cause pain on the outside of the left arm.

Cancer refers to malignant tumors, which are caused by malignant proliferation of cells. Generally, there is no sign, so pain on the outside of the left arm and upper arm is not a sign of cancer. However, cancer is invasive. As the disease progresses, it can destroy the bone on the outside of the left arm and upper arm, and then pain occurs. Patients can also be accompanied by fatigue, emaciation and other symptoms. But pain on the outside of the left arm and upper arm may also be caused by muscle strain, cervical spondylosis, herpes zoster, etc.

Patients can go to the hospital for physical examination, X-ray examination, histopathological examination, etc. to confirm the diagnosis.
